对称五对角矩阵加箭型矩阵的广义逆谱问题OACSTPCD

This paper studies the generalized inverse spectrum problem of a kind of symmetric pentadiagonal matrix plus arrow matrix.First,the extreme eigenvalues of all principal submatrixes of the matrix are taken as their characteristic data.Second,the geometric properties of conic curve,pentadiagonal matrix and arrow matrix are employed to reconstruct this kind of special arrow banded matrix.Finally,the sufficient conditions for the solution of the problem and the algorithm and examples of the problem construction are given,and the accuracy of the results is verified.
